UnThreat AntiVirus Review

A Full Review of UnThreat AntiVirus

Update: I recommend using a different free antivirus program over this one - UnThreat AntiVirus is no longer being updated by its developers, nor is it available for download from the official UnThreat website. While it's probably still safe to use, I do prefer software that's still maintained like avast! Free Antivirus.

UnThreat AntiVirus is a free antivirus program. It provides a built-in email scanner to scan all inbound and outbound messages, which is really nice.

Although the software itself doesn't seem to update very often, it still able to download new virus definitions when they're available.

UnThreat AntiVirus provides constant virus protection, also called on-access or resident protection, for free. This means that UnThreat AntiVirus can completely replace antivirus software from companies like McAfee and Norton that charge for their software and for yearly access to updates.

Pros & Cons

The biggest disadvantage of using this program is that it's been discontinued:


  • Automatic updates
  • Quick download and install
  • Provides real-time protection
  • Can automatically quarantine threats
  • Email protection
  • Scheduled virus scans
  • Quick, full, and custom scans


  • No longer maintained by the developers
  • No firewall
  • Doesn't try to install other programs during the initial installation
  • Contains a large advertisement

More Information on UnThreat AntiVirus

Though UnThreat AntiVirus is now a discontinued product, it does provide lots of great features:

  • UnThreat AntiVirus should work with all recent versions of Windows
  • Features real-time protection against viruses in the file system and email
  • The ability to check files when they're read/copied/written can be disabled
  • Can enable or disable the detection of low-risk threats
  • Known malicious programs can be blocked and sent to quarantine automatically, or you can choose to be notified of them and take action manually
  • You can choose the file extensions that UnThreat AntiVirus should monitor, or have it check every single file regardless of its extension

  • Quick scans and full scans can be customized, like to automatically clean infected files, enable rootkit detection, scan inside archives, use heuristic scanning methods, scan for cookies and adware, scan the registry, and scan running processes. They can also be customized to scan slower to save on system resources
  • Scans can be scheduled in UnThreat AntiVirus to run each time the computer starts up or every day, once a week, or every 1/2/4/8/12 hours. The aforementioned areas can be setup in a scheduled scan too, as well as the ability to scan just certain folders
  • Email protection can be toggled on and off
  • A scan can be setup to run automatically after an automatic update

My Thoughts on UnThreat AntiVirus

I found UnThreat AntiVirus really easy to use. The program layout isn’t hard to grasp and it’s easy to scan files and folders from the right-click context menu.

Outbound emails that UnThreat scans are marked with a message that says they were scanned with the antivirus program. You can remove this from the Email Protection options in the settings.

Something I didn’t like about UnThreat is that a large advertisement to upgrade to the paid version is always present at the bottom of the program that you can’t minimize or exit.

UnThreat AntiVirus Alternatives

There are so many alternatives to UnThreat AntiVirus that you should never feel like you must pay for antivirus software, especially just because UnThreat no longer offers such a program.

Like I said above, UnThreat AntiVirus is still being updated to provide a defense to viruses and other malware, but there are some alternatives you may prefer.
